I did some looking around and this is what I found. You can incubate cricket eggs at room temp (74) but it will take roughly 26 days. Incubating around 86 degrees will give you hatched crickets in about two weeks. Mine have been incubating around 78-80 so I'm guessing mine might hatch in 20 days (5 days in, so that's 15 to go.)

Maybe I'll set up my snake egg incubator and incubate them in there at 86. Ugh, can't wait to get some roaches!
